0.45 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One transparent 0.45 carat oval blue sapphire, dimensions 5.36 x 3.44 x 2.78 mm, presents a technically refined profile that will stand out in any jewelry setting. The mixed brilliant cut combines a finely faceted crown with a pavilion that favors brilliant style facets, creating a lively balance between pinpoint scintillation and broad color saturation. The stone exhibits a length to width ratio of approximately 1.56, producing an elegant oval outline that visually increases apparent surface area compared with round stones of equivalent weight. The measured depth yields an effective depth percentage of approximately 63 percent relative to the average diameter, an optical proportion that optimizes light return while maintaining strong color transmission. Clarity is graded as very slightly included when evaluated at eye level, meaning natural inclusions are present but do not materially interrupt light performance or overall brilliance. Polish is excellent, with crisp facet planes and well defined facet junctions that maximize specular reflections and contrast patterns. Origin is Ceylon Sri Lanka, and the sapphire is natural without enhancement, a provenance and treatment status that enhances collector value and ensures authentic color chemistry.

Color is medium in intensity, a vivid and cool blue with subtle violet overtones typical of fine Ceylon material, and the mixed brilliant faceting accentuates both hue saturation and lively scintillation. The gem displays modest pleochroism, yielding slightly different blue tones as it tilts under light, which creates dynamic color play in wearable settings. In practical terms this sapphire will register as a vibrant focal point whether set as a solitaire, a halo piece, or an east west mounted accent, because its polished facets and optimized proportions channel light into both return and dispersion rather than leaking color back into the body. For metal selection, white gold or platinum will emphasize the crystalline sparkle and perceived coolness of the blue, while warmer metals will create compelling contrast that increases visual impact. At The Natural Sapphire Company we value cut geometry and natural treatment status, and this 0.45 carat Ceylon oval is presented to suit bespoke settings where precision faceting, stable medium color intensity, and untreated origin are prioritized, ensuring the stone reads as distinctly vibrant on the finger and translates effectively into an eye catching finished jewel.
